TACK FASTENED BUTTON Application led January 2, 1932. Serial No.584,516.

The object of this invention is to provide a compensating anvil andfiller or a combination anvil and filler for tack-fastened buttons,which may be usefully and eiciently `applied in either an ordinaryrelatively short hubbed button or a relatively long `hubbed button;these long hubbed buttons being designed to accommodate a modern form ofbuttonhole which is reinforced and has a relatively thick edge. To placewithin this `elongated hub or shankthe ordinary type of one piece anvilfiller is to offer too deep an anvil chamber to cooperate with the tackand make sure of a perfect upsetting of the tack .15point and close fitthereof in its receiving chamber in the anvil.

There is danger also that the assembled button will have a loose andwaggling or wabbling effect and may even twist apart from the tack.

In order to meet the objections noted and others, the present inventionconsists of a compensating anvil and filler or a combination anvil andfiller, designed specially for use in a button having a relatively longshankor hub, but .which is also applicable to a button having a hub orshank of ordinary length, the anvil having a relatively small tack-endclinching and receiving chamber at one end and spread-out fingers Vatthe opposite end, which .fingers may be and preferably are resilient andare adapted toengage or Contact with the inner surfaces of the hub orshank, to guide the tack point into the tack chamber and to provide acertain springiness to take up adjustments in case there should be anunusually long pointed or stiiftack'usedin the assembly, as I willproceed now more fully to explain and finally claim.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a topplan view; Fig. 2 is a side elevation; Fig. 3 is a bottom plan view andFig. 4 is a vertical section of the improved form of compensating anviland filler or combination anvil and filler. Fig. 5 is a vertical sectionof the anvil and filler assembled in a tackfastened button having a longshank or hub the restricted portion 9 are the `laterally yadjustments incase there should be anl unand set upon a piece of fabric. Fig. 6 is anenlarged plan view of a blank such as may be used in forming thecompensating anvil and filler or the combination anvil and filler. yFig. 7 is a top plan view; Fig. 8 is a bottom plan view and Fig. 9 is aside elevation of a modification in which the filler element is extendedlaterally beyond the tack-receiving chamber. Fig. 10 is a verticalsection of the anvil and filler of Figs. 7, 8 and9, assembled in atack-fastened button having a long shank or hub.

In Figs. 1 to 5, inclusive, the back of the button has the relativelylong hub or shank l, depending from the lateral flange 2, and providedwith a bottom 8 made with the opening 4 for the insertion of the tackpoint. Applied to the lateral flange of the tack is any suitable finishcap-5.

Fitted within the shank or hub is the compensating anvil and filler orthe combination anvil and filler, designated generally by the referencenumeral 6, and havingthejlaterally extended portion 7 provided with aflat top 8 on which the finish cap 5 rests. The bottom of the laterallyextended portion 7 is constricted, as at 9, thereby forming within thetop of the device a` relatively small tack point receiving and clinchingchamber 10. Below spread lingers 1l of a length preferably sufficient torest upon or adjacent to the bottom of -the hub and contacting with thesides Vof the hub. The portion 7 is of a diameter to fit comparativelysnuglywithin thetop of the hub andthe spread of the fingers l1 is suchas to overcome any tendency of displacement or wabbling or waggling.These fingers 1l may be more or less resilientk in order to take upusuallyv long pointed or stiff tack used in the assembly orsetting ofthe button.

As shown in Figs. 6 to 10 the compensating anvil and filler orcombination l anvil and filler may have the upper .portion of the tackpoint receiving and clinching chamber 12 extended laterally-as at 13 toform in itself the filler element; and` to compensate for the thicknessof thematerialin this form ofthe construction, the center, portion oftheout- 100 the attaching machine.

side or top may be indented as at 14:. The constricted bottom of thetack clinching and receiving chamber is shown at 9', and the laterallyextending lingers are shown at 11.

The back and cap of the button may be of relatively thin metal, but thecompensating anvil and filler or the combination anvil and illerpreferably is of thick hard metal that will withstand the blowsnecessary to clinch the point of the tack 15 against the anvil andthereby to upset or curl it within the tack point clinching andreceiving chamber, substantially as indicated at 16, Fig. 5.

In addition to the adjustment features previously mentioned, it is to benoted that the same function will be observed in making allowance forvariations in the adjustment of If, for example, the machine is set fora double thickness of fabric but should be applied to a triple orquadruple thickness, or its equivalent, in especially thick goods, therewould undoubtedly be an excessive amount of squeezing between the huband the tack which would tend to cut into the fabric. The spring-likeform of the fingers will take up such extra pressure by collapsing ofthe filler within the hub and thus avoid the excessive constrictionbetween the tack and the outer surface of the hub.

Moreover, the fingers 11 or 11 may be made more or less long in order toaccommodate the device to buttons having hubs of various lengths. Y

In the two forms of the invention there are shown four lingers, butthere may be more or fewer of such lingers.

In Fig. 5, the part 17 may represent an article on which the button isset.

The blank shown in Fig. 6 may be drawn or pressed to shape, mere changesin Jforni and size being required to form either type of anvil andfiller.

Variations in the details of construction are permissible within theprinciple of the invention and the scope of the claims following.

Vhat I claim is:

1. A tack-fastened button, having a compensating or combination anviland filler member, and a shank or hub, said member comprising a portionproviding an anvil chamber of less depth than the length of the hub andprovided with a constricted opening for the entrance of a tack point andfingers offstanding from said portion, said member adapted to bepositioned within the button hub with the top portion adjacent to thetop of said hub and its lingers bearing against the inner face of thebottom of said hub to tlhreby position the member axially of the 2. Atack-fastened button, having a compensating or combination anvil andfiller member, and a shank or hub, said member comprising a relativelyshallow tack-receiving and clinching chamber provided with a restrictedentrance and having depending laterally extending lingers, the upperportion of the said chamber and the entire length of the lingers beingconfined Within the hub.

3. A tack-fastened button, having a compensating or combination anviland filler member, and a shank or hub, said member comprising arelatively shallow tack-receiving and clinching chamber provided with arestricted entrance and having depending laterally extending fingers,the upper portion of the said chamber and the entire length of thefingers being confined within the hub and held against wabbling thereinand adapted for use with a long hub.

4f. A tack-fastened button, having a compensating or combination anviland ller member, and a shank or hub, said member comprising a relativelyshallow tack-receiving and clinching chamber provided with a restrictedentrance and having depending laterally extending fingers, the upperportion of the said chamber and the entire length of the fingers beingconfined within the hub, said chamber laterally confined within the hub.

5. A tack-fastened button, having a compensating or combination anviland filler member, and a shank or hub, said member comprising arelatively shallow tack-receiving and clinching chamber provided with arestricted entrance and having depending laterally extending fingers,the upper portion of the said chamber and the entire length of thefingers being coniined within the hub, said chamber laterally andaxially confined within the hub.

6. A tack-fastened button, having a shank or hub and a compensating orcombination anvil and filler member, said member comprising a relativelyshallow tack-receiving and clinching chamber provided with a restrictedentrance and having depending laterally extending fingers, a portion ofthe said chamber and the entire length of the fingers being conlinedwithin the hub, the upper portion of said chamber being laterallyextended to form a filler element.

In testimony whereof I have hereunto set my hand this 28th day ofDecember, A. D
